Light clusters in warm magnetized stellar matter: equation of state and thermodynamic response
Luigi Scurto, Stefano Burrello, Maria Colonna
Finite-temperature equations of state (EOSs) with a controlled treatment of composition-dependent effects are becoming increasingly important for modeling proto-neutron stars and b…
Connecting the nuclear EoS to the interplay between fusion and quasifission processes in low-energy nuclear reactions
H. Zheng, S. Burrello, M. Colonna +2
Within the Time Dependent Hartree Fock (TDHF) approach, we investigate the impact of several ingredients of the nuclear effective interaction, such as incompressibility, symmetry e…
Interplay between low-lying isoscalar and isovector dipole modes: a comparative analysis between semi-classical and quantum approaches
S. Burrello, M. Colonna, G. Colò +4
We perform Time Dependent Hartree-Fock (TDHF) calculations to investigate the small amplitude dipole response of selected neutron-rich nuclei and Sn isotopes. A detailed comparison…
Pre-equilibrium effects in charge-asymmetric low-energy reactions
H. Zheng, S. Burrello, M. Colonna +1
We study the pre-equilibrium dipole response in the charge-asymmetric reaction Sn+Ni at MeV/A, within a semi-classical transport model employing effecti…
Investigation of collective radial expansion and stopping in heavy ion collisions at Fermi energies
Eric Bonnet, Maria Colonna, A. Chbihi +3
We present an analysis of multifragmentation events observed in central Xe+Sn reactions at Fermi energies. Performing a comparison between the predictions of the Stochastic Mean Fi…
Reaction mechanisms in transport theories: a test of the nuclear effective interaction
M. Colonna, V. Baran, M. Di Toro +2
We review recent results concerning collective excitations in neutron-rich systems and reactions between charge asymmetric systems at Fermi energies. Solving numerically self-consi…
Fragmentation paths in dynamical models
M. Colonna, A. Ono, J. Rizzo
We undertake a quantitative comparison of multi-fragmentation reactions, as modeled by two different approaches: the Antisymmetrized Molecular Dynamics (AMD) and the momentum-depen…
Isospin Dynamics in Heavy Ion Collisions: from Coulomb Barrier to Quark Gluon Plasma
M. Di Toro, V. Baran, M. Colonna +11
Heavy Ion Collisions (HIC) represent a unique tool to probe the in-medium nuclear interaction in regions away from saturation. In this report we present a selection of new reaction…
Investigation of Low-Density Symmetry Energy via Nucleon and Fragment Observables
H. H. Wolter, J. Rizzo, M. Colonna +4
With stochastic transport simulations we study in detail central and peripheral collisions at Fermi energies and suggest new observables, sensitive to the symmetry energy below nor…
Collective modes of asymmetric nuclear matter in Quantum HadroDynamics
V. Greco, M. Colonna, M. Di Toro +1
We discuss a fully relativistic Landau Fermi liquid theory based on the Quantum Hadro-Dynamics () effective field picture of Nuclear Matter ({\it NM}). From the linearized kin…
Instabilities in a Mean-field dynamics of Asymmetric Nuclear Matter
V. Greco, V. Baran, M. Colonna +3
We discuss the features of instabilities in asymmetric nuclear matter, in particular the relation between the nature of fluctuations, the types of instabilities and the properties…
Strong enhancement of extremely energetic proton production in central heavy ion collisions at intermediate energy
P. Sapienza, R. Coniglione, M. Colonna +27
The energetic proton emission has been investigated as a function of the reaction centrality for the system 58Ni + 58Ni at 30A MeV. Extremely energetic protons (EpNN > 130 MeV) wer…
Asymmetric nuclear matter in a Hartree-Fock approach to non-linear QHD
V. Greco, M. Colonna, M. Di Toro +2
The Equation of State (EOS) for asymmetric nuclear matter is discussed starting from a phenomenological hadronic field theory of Serot-Walecka type including exchange terms. In a m…
Fock exchange terms in non-linear Quantum Hadrodynamics
V. Greco, F. Matera, M. Colonna +2
We propose a method to introduce Fock term contributions in relativistic models of fermions coupled to mesons, including self-interactions for the mesonic fields. We show that effe…
